freetype vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 10.04 LTS
- Ubuntu 8.04 LTS

Summary:

FreeType could be made to crash or run programs as your login if it opened
a specially crafted file.

Software Description:
- freetype: FreeType 2 is a font engine library

Details:

Mateusz Jurczyk discovered that FreeType did not correctly handle certain
malformed BDF font files. If a user were tricked into using a specially
crafted font file, a remote attacker could cause FreeType to crash or
possibly execute arbitrary code with user privileges.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.10:
  libfreetype6                    2.4.10-0ubuntu1.1

Ubuntu 12.04 LTS:
  libfreetype6                    2.4.8-1ubuntu2.1

Ubuntu 11.10:

Ubuntu 10.04 LTS:

Ubuntu 8.04 LTS:
  libfreetype6                    2.3.5-1ubuntu4.8.04.10

After a standard system update you need to restart your session to make all
the necessary changes.
